One summer, the men of a working-class, heavily ethnic neighborhood outside Detroit begin to disappear. Even the parish priest mysteriously walks off. Our hero, 16-year-old Michael Smolij, and his pals say they've gone to the moon. After introducing Please Don't Come Back from the Moon's intriguing premise, though, Dean Bakopoulos settles into a more familiar coming-of-age story very familiar, alas about young men making their way in a world of absent or dispensable father figures and encountering women who are either inscrutable or endlessly patient with these men-children. ''These things never go like you imagine they'll go,'' one single-mom girlfriend tells Michael, now in his mid-20s. ''Dreams never do.'' Here's my dream: a more integrated narrative vision worthy of Bakopoulos' considerable talent for capturing young-male ennui.
